what is the mass of salt deposited if at 70\deg celsius 15.0gram of potassium trioxochlorate(v) saturates 50 centimeter cube, at 25\deg celsius 10.0gram of the salt saturate 40 centimeter cube of the salt is cooled from 70\deg celsius to 25\deg celsius

the maximum mass of nh3 is nh3 in grams

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
